我正在嘗試在C中序列化一組結構.這適用于除我的struct中包含的向量之外的所有數據.我可以將數據寫入磁盤,然后將所有數據讀回內存.唯一的問題是當我嘗試訪問向量的元素時,我得到了一個分段錯誤.我的代碼如下.任何幫助是極大的贊賞.

程序寫入磁盤

int main {

struct Student one;

strcpy(one.FullName,"Ernestine Waller");

strcpy(one.CompleteAddress,"824 Larson Drv,Silver Spring,MD 20910");

one.Gender = 'F';

one.LivesInASingleParentHome = true;

one.grades.push_back(80);

one.grades.push_back(90);

ofstream ofs("fifthgrade.ros",ios::binary);

ofs.write((char *)&one,sizeof(one));

ofs.close();

}

程序從磁盤讀取

int main {

struct Student *two = (struct Student *) malloc(sizeof(struct Student));

ifstream ifs("fifthgrade.ros",ios::binary);

//cout << "Size of struct: " << size << endl;

ifs.read((char *)two,sizeof(struct Student));

cout << "Student Name: " << two->FullName << endl;

cout << "First Grade: " << two->grades[0] << endl;

cout << "Second Grade: " << two->grades[1] << endl;

ifs.close();

return 0;

}
